Let 
be a function defined by :
Where [t] is the greatest integer less than or equal to t. Let m be the number of points where f is not differentiable and 
. Then the ordered pair (m, I) is equal to :
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Clearly f (x) is not differentiable at
x = 2, 3, 4, 5 
m = 4
